Turbo squeal

Hey guys I am ready to go get a 7.3! I am having a problem with my truck that sounds like a turbo squeal, it is an intermittent noise and any fluxuation in the throttle causes it to go away. Sometimes it does it a idle and others it will do it at 1/8th throttle. It sounds just like squeaking brakes rolling up to a stop sign but doesn't stop until I give it more or less throttle. Any ideas? Is it a turbo bushing or something to that nature going bad??

Is it possible it could be a problem with one of the vanes in the turbo itself. And as you give it more or less throttle you are causing a difference in boost, which is opening and closing the vanes?

Yep, just went and looked at it and sure does have a crack! Now if I could only get the tranny issues figured out I would be good...
